1.0 MEANING OF SAFETY SIGNAL WORDS
A safety related message is identified by a safety alert symbol and a signal word to indicate the level of risk involved with a particular
hazard. Per ANSI Z535.6, the definitions of the four signal words are as follows:
2.0 SAFETY
DANGER
DANGER indicates a hazardous situation which, if not avoided, will result in death or serious injury.
WARNING
WARNING indicates a hazardous situation which, if not avoided, could result in death or serious
injury.
CAUTION CAUTION indicates a potentially hazardous situation which, if not avoided, could result in minor
or moderate injury.
NOTICE
NOTICE is used to address practices not related to physical injury.
DANGER
An inadequate supply of pressure and/or flow will cause an ineffective stream and can result
in injury or death. Choose operating conditions to deliver adequate fire suppression. See flow
graphs.
WARNING
This equipment is intended for use by trained personnel for firefighting. Use of this equipment for
other purposes may involve hazards not addressed by this manual. Seek appropriate guidance and
training to reduce risk of injury.
WARNING
Equipment may be damaged if frozen while containing significant amounts of water. Such damage
may be difficult to detect visually. Subsequent pressurization can lead to injury or death. Any time
the equipment is subject to possible damage due to freezing, it must be tested and approved for
use by qualified personnel before being considered safe for use.
WARNING
Failure to restrain nozzle reaction can cause injury from loss of footing and/or stream protection.
Opening and closing other nozzles, hose line kinks, changes in pump settings, nozzle pattern, or
flushing will cause changes in nozzle reaction. Nozzle operator must always be prepared in the
event of these changes.
WARNING
Application of water or foam solutions on energized electrical equipment could cause
electrocution. Serious injury or death could result. Assume circuits are energized until confirmed to
be de-energized. Do not apply water or foam to energized electrical equipment.
WARNING
The stream exiting a nozzle is very powerful and capable of causing injury and property damage.
Make sure the nozzle is securely attached and pointing in a safe direction before water is turned on.
Do not direct water stream to cause injury or damage to persons or property.
NOTICE
To prevent mechanical damage, do not drop or throw equipment.

6.0 COMBINATION NOZZLE CONTROLS
6.1 PATTERN CONTROL
TFT nozzles have full pattern control from straight stream to wide fog. Turning the stream shaper clockwise (as seen from the operating
position behind the nozzle) moves the shaper to the straight stream position. Turning the shaper counterclockwise will result in an
increasingly wider pattern.
Since the stream trim point varies with flow, the stream should be “trimmed” after changing the flow to obtain the straightest and farthest
reaching stream. To properly trim the stream, first open the pattern to narrow fog. Then close the stream to parallel to give maximum
reach. Turning the shaper further forward will cause stream crossover and reduce the effective reach of the nozzle.
6.2 FLUSH CONTROL
Small debris passes through the debris screen (if so equipped) and may get caught inside the nozzle. This trapped material will cause
poor stream quality, shortened reach, and reduced flow. To remove small debris, the nozzle may be flushed as follows:
While still flowing water, rotate the shaper counterclockwise (as viewed from behind the nozzle) to the flush position. This will open
the nozzle allowing debris to pass through. Increased resistance will be felt on the SHAPER as the nozzle goes into flush.
During flush the nozzle reaction will decrease as the pattern becomes wider and the pressure drops. The nozzle operator must be
prepared for an increase of nozzle reaction when returning the nozzle from the flush position to retain control of the nozzle.
Rotate the shaper out of flush to continue normal operations.
6.3 STANDARD/LOW PRESSURE KNOB (MAX-FORCE)
For situations where 100 psi at the nozzle is impractical, the Max-Force dual pressure knob may be switched to low pressure mode. In
the low pressure mode, the nozzle pressure is reduced by about 50%, while maintaining a usable stream and increasing the flow. The
nozzle operator must be prepared for a change in reaction when changing modes.
To switch to the low pressure mode, shut off water flow to nozzle and turn knob at front of nozzle counterclockwise (when viewed from
front). Nozzle will now operate at reduced pressure. Repeat the process, except turn knob clockwise, to return to 100 psi operation.
CAUTION Dents or nicks in the nozzle tip can seriously affect the stream reach or pattern, which may increase
the risk of injury due to exposure. Care must be taken to avoid dents or nicks in the nozzle tip.
NOTICE
Turning the shaper further forward will cause stream crossover and reduce the reach of the nozzle.
WARNING
Large amounts or pieces of debris may be unflushable and can reduce the flow of the nozzle
resulting in an ineffective flow. In the event of a blockage, it may be necessary to retreat to a safe
area, uncouple the nozzle and remove debris.

8.0 MAINTENANCE
TFT products are designed and manufactured to be damage resistant and require minimal maintenance. However, as the primary
firefighting tool upon which your life depends, it should be treated accordingly. To help prevent mechanical damage, do not drop or throw
equipment.
8.1 FIELD LUBRICATION
All Task Force Tips nozzles are factory lubricated with high quality silicone grease. This lubricant has excellent wash out resistance,
providing long term performance in firefighting nozzles. If your agency has unusually hard or sandy water, the moving parts of the nozzle
may be affected. Foam agents and water additives contain soaps and chemicals that may break down the factory lubrication.
The moving parts of the nozzle should be checked on a regular basis for smooth and free operation, and for signs of damage. IF THE
NOZZLE IS OPERATING CORRECTLY, THEN NO ADDITIONAL LUBRICANT IS NEEDED. Any nozzle that is not operating correctly
should be immediately removed from service. The nozzle can be returned to the factory at any time for a complete checkup and re-
lubrication with silicone grease.
The field use of Break Free CLP (spray or liquid) lubricant will help to temporarily restore the smooth and free operation of the nozzle.
These lubricants do not have the washout resistance and long-term performance of the silicone grease. Once Break Free CLP is
applied, re-application will be needed on a regular basis until the nozzle can be returned to the factory for a complete checkup and re-
lubrication with silicone grease.
8.2 SERVICE TESTING
In accordance with NFPA 1962, equipment must be tested a minimum of annually. Units failing any part of this test must be removed
from service, repaired and retested upon completion of the repair.
8.3 REPAIR
Factory service is available with repair time seldom exceeding one day in our facility. Factory serviced equipment is repaired by
experienced technicians, wet tested to original specifications, and promptly returned. Any returns should include a note as to the nature
of the problem and whom to reach in case of questions.
Repair parts and service procedures are available for those wishing to perform their own repairs. Task Force Tips assumes no liability for
damage to equipment or injury to personnel that is a result of user service. Contact the factory or visit the web site at tft.com for parts
lists, exploded views, test procedures and troubleshooting guides.
Performance tests shall be conducted on the equipment after a repair, or anytime a problem is reported to verify operation in accordance
with TFT test procedures. Consult factory for the procedure that corresponds to the model and serial number of the equipment. Any
equipment which fails the related test criteria should be removed from service immediately. Troubleshooting guides are available with
each test procedure or equipment can be returned to the factory for service and testing.
9.0 EXPLODED VIEWS AND PARTS LISTS
Exploded views and parts lists are available at tft.com/serial-number.
CAUTION Aerosol lubricants contain solvents that can swell O-Rings if applied in excess. The swelling can
inhibit smooth operation of the moving parts. When used in moderation, as directed, the solvents
quickly evaporate without adversely swelling the O-Rings.
CAUTION Any alterations to the product or its markings could diminish safety and constitutes a misuse of
this product.
NOTICE
All replacement parts must be obtained from the manufacturer to assure proper operation of the
device.
